To all whom it may concern 5 Be itknown that we, AUG ST GaNIER andCHARLES P. OLEsoN, citizens of the United States, residing at St. Paul,in the county of Ramsey and State of Minnesota, have invented certainnew and useful Improvements inPrinting Devices for BookbindersPress-Marks, of which the following is a specification.

Our invention relates to improvements in printing devlces forprlntingbookblnders" press marks upon the forms or signatures of a book whilethe same are being printed.

In bookbinding the order in which the folded setsof sheets, orsignatures as they are called, are to be arranged is indicated by asignature number which is printed upon each sheet as the same goesthrough the press, so that when the sheets are folded into signaturesfor binding the signature numher will be at the bottom of the outsidepage of the signature. The signatures are then assembled in the orderindicated by the successive numbers. In order to avoid the necessity ofexamining each of these numbers to see that the signatures are properlyassembled a press mark is sometimes placed upon the back fold of eachsignature at a distance from the head of the signature which will varyaccording to the position the signature is to occupy in the boundvolume, so that these marks will stand in regular gradations and form abroken line extending diagonally. across the folded back edges of theassembled signatures, and the absence of any mark or the presence of toomany can be seen at a glance by a visual proof inspection of the back.These marks have been applied to the signatures after the same have beenprinted and folded,

but such subsequent application of the marks deprives them of any valuein detecting inaccuracies or irregularities in printing'or folding thesheets, and does not entirely obviate thenecessity of examining thesuccessive signature numbers to make sure that all those of the samenumber have been collected into their own pile.

It is the object of the present invention to provide improved means foraccurately, and conveniently printing these signature marks upon thesignature sheets as thejsame are-passed through the press and,

which is used for printing the'mark does not have to be removed from thechaseas the successive signatures are printed, but can be readilyshifted and adjusted to the positi.onsrequired for the succeeding signatures, and. whereby themark shall beso accurately placed as toenable theoperator to detect errorscinfeeding the sheet through the press, or-infolding the same, by inspection of themarks upon the foldedback edge ofthe signatures." i

. More 'particularly 'thefinvention consists in the construction,combination, and arrangement of jparts hereinafter described andclaimed; j

In the accompanying drawings representing. the preferred embodiment ofthe in- Z vention, Figure 1 is a-perspective view of the improved typeholder with some parts broken away; Fig. 2 is a longitudinal sectionthrough the middle of a fragmentrof thetype holder; Fig. 3 isaperspective view of one of the sliding type; Figs.4 and 5 areperspective views of modified forms of type ends which can used forthesecond and third rows of signatures, respectively; Fig.

6 is a detail of the spring pressed adjusting pinv for the type; andFig. 7 is a perspective view of a pile ofv slgnatures assembled forb1nd1ng,show1ng press marks upon the back.

As shown in Fig.1, thetype holder com- I prises a bar 2having alongitslongitudinal middle a slot 8 which is preferably widened or undercut atthe base, so as to beT-shaped in section. Constructed to slidewithii'ithis slot is atype a with a widened or flanged;

base 5 adapted to fit within the undercut channel in the .base of theslot. This type has a type face 6, of convenient length and width forthe press mark to be printed.

Upon the face of the type holder are a sucg cession of spacing marks 7arranged at a distance apart approximately equal to the length of thetype face 6. The spaces between the spacing marks are numberedconsecutively from One up as. a guide for setting the type. The typeisheld in adjusted positions so that its face will register with any ofthe numbered spaces uponthe holder, by means ofa pin 8 which extendsdown through the type and is adaptedto fit holder and at-the other endagainst a shoulder 12 on the pin. The holes 9 are equal in number to thespaces upon the face of the holder, and are so positioned that thetypefacewill register with one of the numbered spaces whenever the pinfits into a hole. The holder has at one end a spur headed extensionscrew l3whereby it can be made to fit the furniture of the chase.

In use,ithetype holder is placed within the frame or chase which carriesthe type for printingthe signature sheet, and made fast therein by meansof the screw 13. The pin '8 of thetype is then drawn up against thepressure of its'spring until it emerges from the hole 9 and clears thebottom of the slot, thus leaving the type free to move. The'type is thenmoved along the slot until its face registers with the space bearing thesame number as the signature number of the sheet to be printed. If thesignature is tobe placed at the beginning of thebook, the type will beadjusted in the slot so that its face will register with the spacenumbered One on the holder. When the type has reached this position, thepin, if released, will spring down into the hole provided for the spacenumbered One, thereby locking the type firmly in the position at whichit has been set. The type face for'the press mark can then be inked withthe other type in thechase, and, as the sheets A are passed through thepress, will print at the line of fold a mark 14 of the same length asthe type face, or, in other words, of the same length as one of thespaces upon the holder. When the next succeeding signature sheets aretobe printed, the type will be moved back one space so that its facewill register with the space numbered Two, and the "secondsheets will beprinted as above described.

The holder is made preferably of the same length as the printed page, sothat the press marksupon the backs of the signatures will extend in acontinuous, but broken, line from the top of the volume to the bottomthereof. If, now, more signatures are required to complete the book, itwill be necessary to begin over again at the topfor a second pile ofsignatures. In order to distinguish these 60 I signatures from thosefirst placed, a type may be used which has two separated face-parts15,as illustrated in Fig. 4. If a third pile or row of'signaturesbecomes necessary, a type may be used which has three separated faceparts 16, as shown in Fig. 5. In

this way it is possible to distinguish whether the signature belongs tothe second or third pile, it being impossible to distinguish merely bythe position of the mark with reference to the top of the page. In thedrawings, 17 indicates the press mark made by the use of the two-facedtype shown in Fig. 4:, while 18 indicates the press mark made by the useof the three-faced type shown in Fig. 5.
